To facilitate your building project and the City’s permit process, as well as to provide a consistent level of customer service, submittals for building permits must be complete at the time of application. The following documents are required at the time of building permit submittal so that all City departments may complete their plan reviews and grant approval for your project. Permitting time will depend on the complexity of the project, completeness of the plan submittals, and the number of other project submittals received prior to yours. If you have questions or concerns regarding your project, we provide a pre-design process and will schedule a preliminary meeting with your design team to answer questions and assist you in the application process.

Two complete sets of plans, specifications, and submittal documents are required at the time of permit application (one full size scaled set and one 11”x17”). Plans, documents, and specifications must be prepared in accordance with Minnesota Statute 326, Minnesota Rules 1800 and 1805.
